Rationale And Objectives: To evaluate the outcome of diagnostic breast MR imaging followed by MR guided needle localization for mammographically and sonographically occult breast lesions in a community-based hospital.

Materials And Methods: Records of the initial 50 consecutive patients who underwent MR guided needle localizations at our institution from November 2001 to January 2003 were reviewed. Sixty-two lesions were localized by MR and were mammographically and sonographically occult. Pathology following excision was reviewed and correlated with the MR findings.

Results: Cancer was present in 15 % (9/62) of lesions or 18 % (9/50) of the women localized. Five of the lesions (56%) were invasive carcinoma and four (44%) were ductal carcinoma in situ (DCIS). High-risk lesions, including atypical ductal hyperplasia (ADH) and atypical lobular hyperplasia (ALH), were found in 6.5 % (4/62) of the lesions, while 3 % (2/62) of the lesions contained lobular carcinoma in situ (LCIS). Cancer plus high risk lesions were found in 15/62 (24%) lesions or 14/50 (28%) of women who underwent biopsy.

Conclusion: The data in this study supports findings from other studies conducted by large research institutions. In this regard, it is important that community-based hospitals, such as the one operating this breast MR program, can achieve the same positive predictive values as those found in data emanating from academic institutions.
